The forward end of leach pawl is slightly notched, that they may be more easily moved when coming in I Contact with the sash C.

lo show the operation of these pawls,.raise the pawl K by handle O, shoving it upward. This will lower and disengage the forward end of pawl T, that the sash may be raised or lowered to the place desired; then let go the handle O, and the upper pawl will fall of its own weight against sash, which pushes rear end of swinging pawl downward, and bringing-the forward partot' pawl T upward and against the sash O, rendering its farther movement in any direction impossible.

Tile dott-ed lines in iig. l show the position of the two pawls when the upper is raised and both are disengaged.

Edy invention has for its object. to furnish a simple, convenient and powerful catch to prevent any movement of sash in any direction after it is fastened, and that will work if fastened on the sash also, or it will prevent any rectilinear movement between the surfaces, provided it is perpendicular.
